Description: Ther 'Xi ng of dyesl n presence of polymerizabl e comj. . id and an i nitiator. The invention relates to a process for fixing dyes on organic materials by means of at least one colourless cationic compound containing at least one polymerizable double bond and at least one polymerization initiator by thermally initiated polymerization. It is known that dyes, preferably those containing reactive groups, can be fixed on organic material, in particular on fibre material, by thermofixing. The practice of dyeing, in particular, with reactive dyes but also with direct dyes has recently led to increased demands on the quality of dyeing and the economy and ecology of the dyeing process. In many cases, fixing of direct and reactive dyes carried out by conventional methods does not meet these demands. As a result, the object of the present invention is to provide an improved process for fixing which can achieve high degrees of fixation and an economically and ecologically optimum dyeing process. It has now been found that this object can be achieved by the inventive process described below. Accordingly, the present invention provides a process for dyeing or printing organic material, in particular fibre material, which comprises applying at least one dye, at least one colourless cationic compound containing at least one polymerizable double bond, and at least one polymerization initiator, and, if desired, further auxiliaries to the organic material, in particular fibre material, and then subjecting it to thermofixing. The process according to the invention is distinguished by the fact that, for example, the dye can be applied together with a colourless cationic compound and a polymerization initiator, and, if desired, further auxiliaries, so that only a single dyeing vat or only a single dyeing liquor or printing paste is necessary and a substantially higher degree of fixation is achieved than in the known processes in which no colourless cationic polymerizable compound is used. It is however also possible to apply the colourless cationic compound, the polymerization initiator and also further auxiliaries, if used, separately after the actual dyeing process and then subjecting them to thermofixing. The process according to the invention significantly reduces the use of auxiliaries and waste water since, for example, after the fixation process according to the invention, no fixing alkali has to be washed off but the dyed or printed fibre material only needs to be dried and possibly rinsed for a short period of time. Fixing according to the invention is carried out, for example, by subjecting an organic fibre material, for example a textile fibre material, after the treatment with a dye in the presence of a colourless cationic compound containing at least one polymerizable double bond and a polymerization catalyst, and, if desired, further auxiliaries to a thermal treatment for a short period of time while it is wet, moist or dry. The treatment of the organic fibre material with a dye according to the definition can be carried out in one of the usual ways, for example in the case of textile fabric by impregnation with a dye solution in an exhaust bath or by applying a padding solution by spraying or by pad-dyeing, or by printing it, for example, in a roller printing machine or film printing machine or by means of the ink-jet printing technique. The polymerization initiators added in the process according to the invention are inorganic or organic peroxides or aliphatic azo compounds which are activated by the heat generated during the thermal treatment and initiate the polymerization. Examples of such polymerization initiators include, for example, 4,4'-azobis(4-cyanopentanoic acid), α,α'-azobis(butyronitrile), azoamides, for example azobis[2-methyl-(l,l-dimethyl-2-hydroxyethyl)propionamide], 2,2'-azobis(2-methylpropiohydroxamic acid), 2,2'-azobis[2-(N-phenylamidino)propane dihydrochloride], 2,2'-azobis(2-methylpropionohydrazide), 2,2'-azobis(N,N-dimethyleneisobutylamidine), 2,2'-azobis(2-amidinopropane dihydrochloride), organic peroxides, for example chloroacetyl peroxide, trichloroacetyl peroxide, benzoyl peroxide, chlorobenzoyl peroxide, benzoyl acetyl peroxide, propionyl peroxide, fluorochloropropionyl peroxide, lauryl peroxide, cumene hydroperoxide, cyclohexanone hydroperoxide, tert-butyl hydroperoxide, di-tert-butyl peroxide, di-tert-amyl peroxide and p-methane hydroperoxide, and also inorganic peroxide compounds, such as hydrogen peroxide, sodium peroxide, alkali metal percarbonates, alkali metal peroxodisulfates or alkali metal perborates, and redox systems known from the relevant literature. The amount of catalysts to be added depends in a known manner on the desired course of the reaction or the desired properties of the polymer. Advantageously, about 0.005 to 20 % by weight, relative to the total amount of polymerizable colourless compounds, are used. Preferred polymerization initiators are 2,2'-azobis(2-methylpropiohydroxamic acid), 2,2'-azobis(2-methylpropionohydrazide), 2,2'-azobis(2-amidinopropane dihydrochloride), 2,2'-azobis[2-(N-phenylamidino)propane dihydrochloride], and sodium perborate. Preference is given in particular to compounds from the group consisting of alkali metal peroxodisulfates, in particular sodium peroxodisulfate and potassium peroxodisulfate, ammonium peroxodisulfate, sodium percarbonate and 4,4'-azobis(4-cyanopentanoic acid). Thermofixing can be carried out in various ways, for example by steaming, high-temperature steaming, thermofixing, microwave or high-frequency treatment. In the process according to the invention, preference is given to the use of thermofixing. The temperature range in the process according to the invention is between 70 and 230°C, preferably between 70 and 180°C, in particular between 90 and 160°C. The duration of the thermal treatment depends on the substrate to be dyed, the dye used, the temperature selected and, in particular, on the type of initiator. It is usually 1 to 10 minutes, preferably 1 to 5 minutes. The dyes suitable for this fixing process include those whose chromophoric systems belong to a wide range of groups, for example the monoazo or polyazo, metal complex azo, anthraquinone, phthalocyanine, formazan, azomethine, nitroaryl, dioxazine, phenazine, stilbene, triphenylmethane, xanthene, thioxanthone, naphthoquinone, pyrenequinone or perylenetetracarbimide series. Examples of particularly suitable dyes are the direct dyes and the reactive dyes. Direct dyes are understood as meaning, for example, those dyes described in Colour Index, 3rd Edition (3rd Revision 1987, including Additions and Amendments up to No. 85) as "direct dyes". Reactiv ayes are understood as meaning those dyes containing one or more reactive groups. They are understood as meaning those dyes described in Colour Index, 3rd Edition (3rd Revision 1987, including Additions and Amendments up to No. 85) as "reactive dyes". Reactive groups are Understood as meaning fibre-reactive radicals which are capable of reacting with the hydroxyl groups of cellulose, the amino, carboxyl, hydroxyl and mercapto groups of wool and silk, or with the amino and, if present, carboxyl groups of synthetic polyamides with the formation of covalent chemical bonds. The reactive groups are usually attached to the dye radical directly or via a bridging member. Examples of suitable reactive groups are those containing at least one detachable substituent on an aliphatic, aromatic or heterocyclic radical or in which the radicals mentioned contain a radical capable of reacting with the fibre material, for example a triazine radical. Examples of reactive groups include radicals containing carbo- or heterocyclic 4-, 5- or 6-membered rings substituted by a detachable atom or a detachable group. Examples of heterocyclic radicals include those containing at least one detachable substituent attached to a heterocyclic radical; they include those containing at least one reactive substituent attached to a 5- or 6-membered heterocyclic ring, such as to a monoazine, diazine, triazine, pyridine, pyrimidine, pyridazine, pyrazine, thiazine, oxazine or unsymmetrical or symmetrical triazine ring, or to such a ring system containing one or more fused-on aromatic rings, such as a quinoline, phthalazine, cinnoline, quinazoline, quinoxaline, acridine, phenazine and phenanthridine ring system. Furthermore, the heterocyclic fibre-reactive radicals mentioned can contain further fibre-reactive radicals, for example the abovementioned radicals, via a direct bond or via a bridging member. Particularly preferred reactive groups are those containing at least one activated unsaturated group, in particular an unsaturated aliphatic group, for example a vinyl, halovinyl, styryl, acrylic or methacrylic group, or at least one polymerizable ring system. Examples of such groups include unsaturated groups containing halogen atoms, such as halomaleic acid and halopropiolic acid radicals, α- or β-bromo- or chloroacrylic groups, halogenated vinylacetyl groups, halocrotonic or halomethacrylic groups. Also suitable are groups which can be easily converted into halogen-containing unsaturated groups, for example by elimination of hydrogen halide, for example the dichloro- or dibromopropionyl group. Here halogen atoms are understood as meaning fluorine, chlorine, bromine and iodine atoms and also pseudohalogen atoms, for example the cyano group. The process according to the invention also gives good results with dyes containing an α-bromoacrylic group. Dyes containing a polymerizable double bond are preferably those containing at least one acryloyl, methacryloyl, α-bromoacryloyl, α-chloroacryloyl, vinyl or vinylsulfonyl radical; particular preference is given to those containing at least one acrylamido, methacrylamido, bromoacrylamido and chloroacrylamido reactive group and very particular preference is given to those containing, independently of one another, at least two acrylamido, methacrylamido, bromoacrylamido and chloroacrylamido reactive groups. Dyes containing a polymerizable ring system are preferably those containing at least one epoxy radical. Examples of other detachable atoms or detachable groups are ammonium, including hydrazinium, sulfato, thiosulfato, phosphato, acetoxy, propionoxy or carboxypyridinium. Suitable bridging members between the dye radical and the fibre-reactive radical or suitable bridging members between two fibre-reactive radicals are, in addition to the direct bond, a wide range of radicals. The bridging member is, for example, an aliphatic, aromatic or heterocyclic radical; furthermore, the bridging member can also be composed of various such radicals. The bridging member usually contains at least one functional group, for example a carbonyl group or an amino group, where the amino group can be further substituted by unsubstituted or halogen-, hydroxyl-, cyano-, C r C 4 alkoxy-, C r C 4 alkoxycarbonyl-, carboxyl-, sulfamoyl-, sulfo- or sulfato-substituted C 1 -C 4 alkyl.

The printing pastes and dyeing liquors can contain, in addition to the dye and the polymerizable compounds and a polymerization initiator, customary additives such as thickeners, dyeing assistants, fillers, dispersants, lubricating agents, antioxidants, antifoams and polymerization inhibitors. The latter are usually also added to the polymerizable compounds as stabilizers. The process according to the invention can be applied to a wide range of fibres, for example fibres of animal origin, such as wools, silks, hair (for example in the form of felt) or semi-synthetic chemical fibres, such as protein fibres, fully synthetic fibres, such as polyvinyl, poly aery lonitrile, polyester, polyamide, aramid, polypropylene or polyurethane fibres and in particular cellulose-containing materials, such as bast fibres, for example linen, hemp, jute, ramie and, in particular, cotton, and synthetic cellulose fibres, such as viscose or modal fibres, cuprammonium, nitrocellulose or hydrolyzed acetate fibre or fibres made of cellulose acetate, such as acetate fibre, or fibres made of cellulose triacete, such as Arnel®, Trilan®, Courpleta® or Tricel®. The fibres mentioned can be present in the forms used in particular in the textile industry, for example as filaments or yarns, or as woven fabrics, knitted fabrics or nonwoven materials, such as felt. The fibre material preferably used in the process according to the invention is wool, silk, hair, polyvinyl, polyacrylonitrile, polyester, polyamide, aramid, polypropylene or polyurethane fibres or cellulose-containing fibres. Cellulose fibres, polyester/cellulose blend fabrics and knitted fabrics and intimate polyester/cellulose fibre blends are particularly preferably used. The treatment of the material to be dyed with a dye according to the definition can take place in the usual manner, for example, in the case of textile fabrics, by impregnation with a dye solution in an exhaust vat or by applying a padding solution by spraying or pad-dyeing, or by printing, for example, in a roller printing or film printing machine or by means of the ink-jet printing technique. The dye and the colourless cationic compounds and the polymerization initiator can be applied jointly as a homogeneous solution, suspension, emulsion or foam using customary methods. The dyed fibre material can be fixed while wet, moist or dry. In general the colourless cationic compounds and the remaining additives are applied together with the dye to the material to be dyed. Alternatively, the colourless cationic compounds or the colourless cationic compounds and/or the polymerization initiator and, if used, further auxiliaries can be applied separately, for example in the form of an aftertreatment. The process is suitable in particular for carrying out continuous dyeing, printing and fixation processes, but the process or individual steps thereof can also be carried out batchwise. The procedure of the process according to the invention is such that, for example, the textile substrate is dyed with a liquor containing a dye, at least one cationic acrylate and at least one thermal initiator and then subjected to a heat treatment, or that a dyeing is treated afterwards with at least one cationic acrylate and at least one thermal initiator and is then subsequently fixed by application of heat. The dye concentrations of the dye solutions or printing pastes used can be selected as in conventional dyeing and printing methods, for example 0.001 to 20 % by weight, relative to the fibre material used. The obtainable degrees of fixation are high, for example more than 90 %. The process according to the invention usually produces dyeings having generally good properties, for example good wet- and light-fastness properties. A preferred embodiment of the process according to the invention involves carrying out not only fixation of the corresponding dyes on the fibre material but also dyeing or printing continuously. The invention also provides preparations comprising a dye, at least one colourless cationic compound containing at least one polymerizable double bond, at least one thermal polymerization initiator and, if desired, a colourless nonionic compound and a solubilizer. Preferred compositions contain those preferred individual components as discussed in the description of the dyes and of the colourless compounds. These compositions can contain further additives such as are customary for dyeing or printing. These compositions are also understood as meaning printing pastes suitable for emulsion printing. Preference is given to preparations comprising (a) 5 - 30 parts by weight of a dye, (b) 5 - 70 parts by weight of a colourless cationic compound containing at least one polymerizable double bond, (c) 0.005 - 5 parts by weight of a thermal polymerization initiator, (d) 0 - 60 parts by weight of a nonionic colourless compound and (e) 0 - 10 parts by weight of a solubilizer, relative to 100 parts by weight of the preparation. Particular preference is given to preparations comprising 10 - 20 parts by weight of component (a), 10 - 60 parts by weight of component (b), 0.01 - 2 parts by weight of component (c), 0 - 60 parts by weight of component (d) and 0 - 10 parts by weight of component (e), relative to 100 parts by weight of the preparation. Very particular preference is given to preparations comprising 10 to 20 parts by weight of a dye as component (a), 10 to 60 parts by weight of a quaternary ammonium salt of the formula (30) as component (b), 0.01 - 2 parts by weight of an alkali metal peroxodisulfate as component (c), 0 to 60 parts by weight of an oligoethylene glycol diacrylate of the formula (31) as component (d) and 0 to 10 parts by weight of urea as component (e), relative to 100 parts by weight of the preparation. In order to prepare a dyeing liquor or a printing paste, the concentrated preparations described can be diluted to any required dye concentration, it being possible for the nonionic colourless component (d), if not already present in the preparations, either to be added to the liquor in concentrations of 50 - 125 g/1 or to be applied to the fibre material already beforehand in concentrations of 30 - 90 g/kg. The examples which follow serve to illustrate the invention without limiting it thereto. Therein parts and percentages are by weight. The temperatures are given in degrees centigrade. Parts by weight relate to parts by volume as the gram relates to the cubic centimetre. The degrees of fixation of the dye are determined via the dye content of the extracts obtained from a thermofixed stamped sample which has not been washed off and from a non-fixed stamped sample which has been dried at room temperature, both of which have a size of (2.5 cm) 2 . The samples are treated once at room temperature with 25 ml of a solution of 600 ml 1 phosphate buffer (pH 7) and 40 ml/1 tetramethylurea in desalted water for 20 minutes and then once at 100°C with 25 ml of this solution for 20 minutes. The two extracts from each sample are combined and measured by spectroscopy. The degrees of •fixation are determined from the extinctions (at λ max ) of the extracts of the corresponding stamped samples.
